More like me buying a (possibly) counterfeit from china. That's what. Since I did buy this one on ebay...
Explain why my deathadder black edition doesn't track (well) on it? It tracked great on the Mantis speed. But who knows...the 3G DA tracks great on it so I could just be wasting $ if I try buying one from razer directly.
I'll get one from razer themselves and see, if they still have the pre-2014 version.
